John McCain can't guarantee that he would back his own vice presidential candidate Alaska Gov. Sarah Palin if she ran for president in 2012, he conceded in a surprisingly weak show of support on ABC's This Week. McCain praised Palin, but repeatedly ducked questions about backing her in a future race.
"She invigorated our campaign. Have no doubt of my admiration and respect for her and my view of her viability, but my corpse is still warm," he said in his first TV news interview since his defeat. "I can't say something like that. We've got some great other young governors."
